Ashaya, Soul of the Wild + Scryb Ranger + Accomplished Alchemist

Ashaya, Soul of the Wild

Scryb Ranger

Accomplished Alchemist

How it works

1. Activate Accomplished Alchemist by tapping it, adding at least .
2. Activate Scryb Ranger by returning it from the battlefield to your hand, untapping Accomplished Alchemist.
3. Cast Scryb Ranger by paying 1.
4. Repeat.

The magic of this loop lies in Ashaya, Soul of the Wild, whose passive ability turns every nontoken creature you control into a Forest land in addition to its other types. This transforms your Scryb Ranger into a valid target for its own ability, allowing you to bounce itself by returning it as a "Forest" to your hand. Once the Ranger is back in your hand, you simply recast it and let Accomplished Alchemist—fueled by the mana you generated—tap for a growing deluge of colored mana.
